I booked with my family, taking four large tents including the Pac Man tent. The biggest problem was one of the tents was covered with black mould and mildew and, worse, leaked in several places. This left my sister, with young children and a baby, afraid to use the electric lights and using cups to catch leaks. I wish I could upload pictures here, because I have them.
Most of the other tents were fine, even though I remain dubious that any of the electrics are safe given that some of them are just patched up with duct tape. I also noticed (when we had a minor injury) that the first aid kit in the kitchen was half empty, with nothing at all to deal with burns (which you'd expect on a campsite). The BBQ when we arrived also had leftover food in it from several days past, so cleaning is an issue.
We complained to the owner, who apologised, promised to look into it and offered to put up a new bell tent for us. Unfortunately the new tent was smaller and had nothing in it - no carpet, no matting, no furniture, making it completely pointless and just as wet, with no ground insulation.
The owner was on site the following day and didn't check in on us even as the rain worsened and despite promising to.
Eventually, the following day, we got in contact with him. He agreed that this was an issue, got carpets, etc. in place. But by then it was the last day and our group was just being downgraded to a worse tent. No refund. No care given. He did offer to open one of the outbuildings so we could have dinner in there, but it was filthy and he rescinded the offer as soon as we said that wouldn't make up for the whole issue.
Terrible experience, would not return. Not suitable for families.
